STOPPERING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 562,065, dated June 16, 1896.

Applicati n filed September 28, 1895. $erial No. 563,944. (No model.)

To aZZ whom it may concern:

Be it known that I, WILTON BROOKE, manufacturing chemist, a subject of the Queen of Great Britain, residing at Ashville, Stairfoot, near Barnsley, in the county of York, England, have invented new and useful Improvements in Stoppering Bottles, of which the following is a specification.

My invention relates to that class of bottles which are stoppered internally by means of a glass globe or stopper and an india-rubber or other ring held in a groove inside the bottlemouth, and more particularly to bottles of such kind or class which are so formed that the stopper can be introduced into the bottle after the latter is made.

In the accompanying drawings, Figure l is a vertical central section of part of a bottleneck, showing also in side elevation one form of my improved stopper partly inserted into the bottle. Fig. 2 is a similar view showing the stopper in the bottle and bearing against the rubber ring therein. Fig. 3 is a vertical central section of part of a bottle-neck, illustrating another modification of my said invention. Fig. 4 is a side elevation of the stopper which I use with the bottle shown in Fig. 3.

According to the method hitherto generally adopted of manufacturing bottles of the kind or class to which my invention relates the stopper is placed in the bottle-neck during the process of making the bottle-that is, be fore the bottle-mouth is completed-and after the bottle is complete it is impossible to extract the stopper without first breaking either the stopper or the bottle. Moreover, when a stopper is broken or starred in the bottle the bottle is rendered useless, as another stopper cannot be introduced into the same.

One object of my present invention is to form the stopper and the interior of the bottle-mouth in such a manner as to permit both the introduction and the removel of the said stopper after the bottle is made, and so that while the stopper can be introduced into the bottle after the latter is made it cannot easily fall out of the same. I thus provide for effecting considerable economy in the manufacture of internally-stoppered bottles, as with the usual method of manufacture a large number of bottles are rendered useless by breakage of or injury to the stoppers after they have been introduced into the bottles I and the bottles have been completed.

Another object of my said invention is to so construct my improved bottle that it can be used for external screw-stoppers or similar external stoppers,and when it is desired to so use the bottle it is only necessary to remove the india-rubber ring and, if desired, screw out or similarly remove the internal stopper, and the bottle is then ready for use with an ordinary screw-stopper carrying an india-rubber ring, which engages with the lip of the bottlemouth and secures the bottle air-tight in the manner already well known.

My said invention consists partly inabottle having projections in the mouth thereof and provided with an internal stopper having corresponding external projections adapted to pass between the projections in the bottlemouth when said stopper is inserted therein and turned about its axis, the plain part of the bottle-neck immediately below said projections being of such internal diameter that the stopper can pass freely through the same, whereby when the stopper is introduced into the bottle it cannot fall out of the same, but can nevertheless be readily withdrawn from and reinserted into the bottle when desired.

My said invention also partly consists in a bottle having, in addition to the usual groove in the bottle-neck for the reception of a rubber ring, an internal screw above said groove in the bottle-mouth, through which a stopper formed with a corresponding external screw or segments of a screw can be introduced into the bottle by inserting it into the bottle-mouth and then turning it about its axis, and in which an external screw-stopper can be secured, the plain part of the bottle-neck immediately below said groove being of sufficient internal diameter to permit the free passage of said internal stopper through it.

In making a bottle according to'my improvements I form a groove in the bottlemouth in the ordinary way for the reception of the india-rubber or other ring, and above this groove Ialso, by means of suitable tools, form an internal screw-thread or inclined planes or segments of a screw-thread or other suitable formations in the bottle-mouth. O11

the stopper I form either screw-threads or projections or studs or other suitable formations which will work through the screwthreads or inclined planes or other formations in the bottle-mouth. To introduce this stopper into the bottle, it is inserted in the bottlemouth and then turned about its axis, so as to cause it to pass right through the screwthreads or other formations in the bottlemouth until the stopper falls into the bottleneck. I then insert the india-rubber or other ringin the ordinary manner and the bottle is then complete, and when it is filled with aerated or gaseous liquid the internal pres sure will force the stopper against the said ring and thus make the bottle air-tight in the well-kn own manner. To release the contents of the bottle, the stopper is removed from its contact with the said ring, as is well understood.

lVhen it is desired to extract the stopper from the bottle, I first remove the india-rubber ring from the bottle-mouth and then invert the bottle and allow the stopper to fall into the bottle-mouth until it can be reached either by the fingers or by a suitable tool, and Ithen screw or otherwise cause the stopper to pass out of the bottle-mouth.

Referring to the drawings, a is the bottleneck. I) is the stopper. 0 is the india-rubber ring, which is fitted, as usual, in a circumferential groove (Z in the mouth of the bottle.

In the arrangement shown in Figs. 1 and 2 the stopper Z) is formed with studs or projections 1), arranged in a spiral or helical row around the same. The bottle-mouth is made with an internal screw-thread (2 above the groove (1, which screw-thread and the other parts of the bottle-mouth are so formed that when the stopper is inserted in the bottlemouth and turned about its axis the said studs or proj eetions b will travel between the threads of the internal screw until they pass out at the lower end thereof, when the stopper will fall into the bottle-neck, the plain part of the bottle-neck immediately below said groove 61 being of such diameter as to permit the stopper to pass freely through it.

It is obvious that although the stopper cannot fall out of the bottle when the latter is inverted yet the said stopper can be readily removed from the bottle, when desired, by turning it in the reverse direction about its axis, so as to screw it through the mouth of the bottle.

To facilitate the turning of the stopper about its axis, I sometimes form a hole or holes 11 in either end of the stopper to permit the insertion of a suitable tool for the purpose, or I provide the stopper with one or more projections at either end, so that it can be more easily turned by hand or otherwise.

In the modification shown in Figs. 3 and at the stopper Z) is made with a screw-thread U extending completely around it.

It will be evident that the bottles shown in the drawings can, when desired, be closed by an external screw-stopper of the well-known or other suitable kind, either with or without previously removing the internal stopper.

My improved internal stopper may be made of glass, earthenware, ebonite, or other suitable substance or substances. It is in all cases made with at least one of its sides convex, and I preferto make it either of approximately spherical form or of elongated form with rounded ends, as shown.

My improvements are applicable to bottles with or without contractions at the base of the neck for preventing the stopper falling to the bottom of the bottle and with or without indents for holding the stopper when the contents are being poured out and when the bottle is being washed, or, if desired, the stopper can be removed when the bottle is to be washed. My improved stopper may also be used with bottles having a valve in the neck.

Instead of forming a screwthread in the hott1e-mouth, as above described, I sometimes make both the bottle-mouth and the stopper with short inclined projections orsegments of a screw-thread, or with other suitable projections, so that the stopper can only be introduced into the bottle by first inserting it into the bottle-mouth, so that its proj ectionspass between some of the projections in the bottle-mouth, and then turning it about its axis through a suitable angle, so as to permit its projections to pass between the remaining projections in the bottle-neck. In any case my bottle and stopper are so constructed that when the projections on the stopper have, in the rotation of the stopper, passed those in the bottle-mouth the stopper can fall freely into the bottle-neck.

hat I claim is 1. A bottle having a circumferential groove in its mouth, carrying a packing-ring, and having internal projections above said groove, the spaces between said projections being of less internal diameter than that part of the bottle-neck immediately below said groove, to permit the insertion or withdrawal, into or from the interior of the bottle, of a stopper having external projections therefrom adapted to pass through the spaces between said internal projections from the bottle.

2. Abottle havingacircumferentialgroove in its mouth, a yielding packing-ring carried thereby, internal projections in the mouth of said bottle above said circumferential groove, and a stopper having projections adapted to register with the spaces between the said internal projections, the external diameter of said stopper across said projections being less than the internal diameter of that part of the bottle-neck immediately below said groove, substantially as and for the purpose described.

3. Abottle having a cireum ferential groove in its mouth, a yielding packing-ring carried thereby, internal screw-thread projections above said groove, a stopper provided with correspondin g serew-thread projections around IIO its periphery, adapted to register with the spaces between the screw-thread projections in the bottle-mouth and of an external diameter less than the internal diameter of that part of the bottle-neck immediately below said groove, substantially as described.

4. A bottle havinga circumferential groove in its mouth, a yielding packing-ring carried thereby and forming a seat for an internal stopper, internal projections from said bottlemouth above said circumferential groove, a stopper having external projections adapted to pass through the spaces between the internal projections in the bottle-mouth, the part of the bottle-neck below said groove being of such a diameter as to permit said stopper to pass freely through it and means at the end of said stopper to facilitate the passage of the same through the bottle-mouth in either direction, substantially as described.

5. A bottle having a circumferential groove in its mouth to receive an india-rubber or other ring or seat for an internal stopper, and having, an internal screw above said groove and a plain part of the bottle-neck immediately below the same adapted to permit the passage into the bottle of an internal stopper having corresponding peripheral projections and also adapted to receive an external screwstopper, substantially as described.

(3. A bottle having a circumferential groove in its mouth, a removable packing-ring in said groove forming a seat for an internal stopper, internal helically-arranged projections above said groove, a plain part of the bottleneck immediately below said groove of suflicient diameter to permit the passage of said stopper through it, a removable internal stopper provided with a valve-surface to cooperate with said ring and having helicallyarranged peripheral projections to engage with the internal projections in the bottlemouth, substantially as described.

7. The combination, of a bottle having in the neck thereof helically-arranged projections, a removable ring or valve-seat below the same and a plain part immediately below said ring or valve-seat of larger internal diameter than the spaces between said projections, a removable internal stopper provided with peripheral projections adapted to pass between said projections in the bottle-neck when the stopper is turned about its axis, and to pass through the plain part below said ring or Valve-seat and with a valve-surface to cooperate with said removable ring or Valveseat, substantially as and for the purposes hereinbefore described.

8. In combination with a bottle having an internal screw-thread, a circumferential groove beneath the same, a removable ring or valveseat in said groove, and a plain part immediately below said groove of larger internal diameter than the spaces between the threads of the screw a removable internal stopper provided with an external screw-thread and with a valve-surface at its end cooperating with said removable ring or valve-seat in the bottle-mouth, substantially as and for the purposes above specified.
